Publication number: 20150196813Abstract: A golf putter grip comprises a main tubular body having a non-circular cross-section being symmetrical and remaining similar throughout its axial length and a flat front area being also along and throughout its axial length. The non-circular cross-section and the flat front area respectively have a width sufficient to have two hands cupped together at the same height and two thumbs placed side by side on the flat front area to hold the putter grip comfortably with minimal wrist breaking-down. The non-circular cross-section can be in a shape of flat-topped arch, flat-topped washer, modified rectangular, modified square, modified triangular, hexagonal and other non-circulars. The main tubular body is reversely tapered, and its reverse taper is sufficient in certain degrees to accommodate different finger lengths of two hands for reducing the gripping pressure, so as to make the gripping comfortable.Type: ApplicationFiled: January 10, 2014Publication date: July 16, 2015Inventors: Hong-Sung Chu, Chiung-Ling Wang Chu

Patent number: 8308581Abstract: A golf club grip having an outer leather layer that includes a low water absorption leather and a polymeric protection coat. The low water absorption leather has a static water absorption range from about 30% by weight to 20% by weight after completely immersed in water for one hour and a range from 45% by weight to 35% by weight after completely immersed in water for six hours in the test method according to ASTM D6015. The protection coat is bonded to a grain surface of the low water absorption leather to retard the penetration of water and to protect the leather from damages. The outer leather layer is configured either as a single sheet or as a strip, wrapped and adhered onto a lining sleeve to cover a sleeve body of the lining sleeve to form a water repellent leather grip.Type: GrantFiled: May 5, 2010Date of Patent: November 13, 2012Inventors: Chien-Kuo Ou, Hong-Sung Chu

Patent number: 6656057Abstract: A golf club grip includes a molded or shaped tubular foam body of closed-cell foam material and an anti-slip rubbery skin bonded integrally to an outer surface of the tubular foam body, thus a slip-on type of this invention is formed. The closed-call foam provides advantages, such as light weight with correct or standard size, a wide range of size and grip weights for personal choice. The tubular foam body has a capped end to cap a grip-mounting portion of a golf club shaft. In an embodiment of coiled strip type, the tubular foam body is cut spirally to form a coiled strip that can be wrapped spirally around the grip-mounting portion, and the capped end is formed as a cap which is integral with the coiled strip.Type: GrantFiled: January 23, 2002Date of Patent: December 2, 2003Inventors: Franco C. Manual, Hong-Sung Chu

Publication number: 20030216192Abstract: A grip for a golf club includes a unitary inner layer tube with a butt cap and a tip ring, made of a resilient polymeric material, and adapted to be disposed around one end of the golf club. An outer layer is disposed around and is adhered to the inner layer tube, and includes a flexible sheet member having two opposite longitudinal ends along an axial direction of the inner layer tube. The sheet member is adhered to the inner layer tube by wrapping the sheet member, in a flat form, around the inner layer tube solely along a circumferential direction relative to an axis of the inner layer tube until one of the longitudinal ends reaches the other one of the longitudinal ends between the butt cap and the tip ring of the inner layer tube. The outer layer includes a plurality of anti-slip stitches thereon.Type: ApplicationFiled: September 16, 2002Publication date: November 20, 2003Inventor: Hong-Sung Chu
